i have a lot of excess energy, even at my age and that could be due to the fact that all my life, i've had adhd--attention deficit hyperactivity disorder. but the great thing about having that, and i don't even think of it as a disorder, i think of it as a benefit because you can hyper-focus on what you love to do. in my case, riding a unicycle. i don't see myself quitting. i see myself riding well into my eighties. i want to be the oldest extreme unicyclist. i probably am at this point. - and what would terry be if he weren't an extreme unicycler? - getting fat. ha ha! for sure. - i'm val zavala for "my generation." - today, terry is one of the few unicyclists in the world over 50 to have successfully jumped and cleared a full set of 8 stairs a 6-foot phone booth and a 7-foot tractor. we totally give it up to you, terry. - be a part of the conversation. send an e-mail to mygeneration@aarp.org or "like" us on facebook and follow us on twitter. - he's a world-class extreme athlete, programmed to put one foot in front of the other to complete the journey. marshall ulrich never knew that
